. HEADLIGET.

Application filed November 3, 1922. Serial No. 598,793.

To all whom t may concer/ni i I Be it known that I, JOHN M. B. Lnwis, acitizen of thev United States, residing at `Lynchburg, inl the county ofCampbell and i State of Virginia, have invented certain new and usefulImprovements in Headlights, of

which the following is a specification.

, This invention relates to headlights and more particularlytoheadlights for automobiles wherein the direct rays of light areprevented from being thrown into the eyes of drivers of automobilesapproaching in the .opposite direction.

i s is well known numerous attempts have been madeto provide non-glareheadlights for automobiles, the usual method being to provide lenseshaving surfaces of peculiar .configuration whereby the rays of light arethrown downwardly. These devices `have not been wholly satisfactorysince acertain amount of the vdirect rays of light are thrown in theeyes of drivers of approaching vehicles. y D

It is an important object of the present` invention to provide aheadlight structure employing a lighting unit and a reflector both ofwhich driver of a `vehicle approaching in the opposite direction.

Other objects and advantages of the/invention will be apparent duringthe course designates, as a whole, `metal lamp casing having of thefollowing description.

In the drawings I have shown one embodiment of the invention. In thisshowing,

Figure 1 isa central vertical longitudinalV sectional view, and, Figure21s a front elevation.

Referring a preferably sheet A a substantially horizontal central upperportion 11', the metal of the lamp Icurving upwardly gas at 12 towardthe front end thereof and terminating in the relatively short horizontalportion 13. As shown in Figure 2 the forward end of the casing issubstantially rectangular and the lamp slopes' downwardly yandrearwardly to a curved and enlarged rear, portion 15. The casing, isadapted to be supported in a bracket 16, be-

' ing adjustably secured thereto by bolts 17.

c opening 20 therein.

'Theforwardf open end of the casing is closed by a door 18 having theusual glass or lens 19. arran ed therein as shown. .The

door 18 has' a re atively narrow rectangular are screened from the viewof a to the drawings the numeral 1 0" the light27 and reflectors 28 ,Thedoor 18 isliinged4 at its upper end to the casing 10 asat 21,

while the lower end thereof is secured to the 22 carried by a stem 23and casing by a nut adapted to engage within forks 24C carried, yby thelower wall 111 of the casing.

u The curved portion 15 of the casing nis p'rovided with a slot 25 -inwhich is mounted the stem 26 of an electric .bulb ory other lightingunit 27. A `parabolic reflector 28 is rigidly secured to the stein 26and the latter, as shown, projects outwardly of theY l casing throughthe slot'25. rI`he'outer portion of the stem-26 is secured to a rod 29,

the outer end of which is threaded as at 30.`

A brackety 31 is secured to the-rear portion j of the casing 10 abovethe stem 26 of the lighting unit, and is provided with an opening inwhich the rod 29 is loosely mounted. Iiocks nuts 32 are threaded uponthe rod 42S) upon opposite sides of thel bracket 32 Awhereby thepositionof the lighting unit andits parabolic reflector maybe adjusted.

A reflector 33 is arranged in the upper portion of the casing as shownin Figure 1,

-the forward portion of the reflector curving4 upwardly as at 34 andterminating at a point space rlhe numeral 35 designates 'a light screenarranged in the upper forward portion of the casing, thescreen beinghinged to Vthe casing as at 36. A threaded arcuate rod 37 is connectedto the forward end of the screen 35 by an eyelet 38 and projectsupwardly casing, anut 39 being threaded upon the upper end of the rod37.

It will be seen in Figure 1 that the lower. and rear end oftherellector'33 is arranged at a point slightly above theupper line of theopening 20 as indicated by line therethrough. rlhe lighting element 27andparabolicrelector 28 are arranged at a position wholly below thelower line of the opening 20 as indicated by the dotted line above theupper end of the reflector 28. It will be apparent that driversofvehicles approaching in protected from the direct rays of light fromtue of their arrangement with respect to the opening 20v in the cover ofthe rays of light being indicated by the dot and dash line in Fi re 1.v"Ihe mountingpof the stem of the light permits adustment 'of the latterwhereby t e paths o the rays of light may be variedl somewhat to fromthe forward end of the casing.-

the dotted the opposite direction are and 33 by vir.

18, the paths through an opening in the portion 13 of the v90 itsforward end, an approximately horiserving as a reflector to reflect raysof light downwardly upon the forward portion of the machine and theground adjacent the forward portion of the machine. y

It is to be understood that the form of my invent-ion herewith shown anddescribed is to be taken as a preferred example of the same and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having described my inventiongI claim:

,1. A device of" the character described comprising a casing having anopening in its .forward end` an approximately,hori; zontally arrangedreflector disposed in the upper portion of said casing wholly above theupper line of said,openin'g,`the forward portion of said reflector beingcurved upwardly, and a lighting unit arranged in the lowerpoition ofsaid casing rearwardly-of said reflector and wholly below the lower lineof said opening. Y2. A device of the character described comprising acasing having an opening in zontally arranged reflector disposed in theupper portion of said casing above the upper line of said opening, theforward por- Ation of said reflector being curved upwardly,

a lighting unit arranged in the lower por- `tion of said casingrearwardly of said re- 'flector and below the lower line of saidreflector having its frwardportion curved upwardly and terminating at apoint spaced from the forward end of said casing, a screen pivotallyconnected at its upper end adjacent the forward end of said reflector,the lower edge of said screen being adapted to be arranged below thelevel of the lowermost portion of said reflector', means foradjnstingsaid screen, and a lighting unit arranged in the loweini'ear portion ofsaid casing wholly. below the lower line of the opening therein.

In testimony whereof, I affix my signature.A
